as they form no part of the present invention, which is limited to thepeculiar construction of the needle itself and the stripper slidablymounted thereon.

The main object of the invention is to provide a cotton stripper whichcan be very cheaply manufactured and applied to a cotton needle orspindle of the type disclosed herein for the purpose of efficientlystripping the cotton from such spindle or needle.

Other objects of the invention will become apparent as the detaileddescription proceeds.

In the drawings: 7

Figure 1 is a side elevation of a cotton needle having the stripperforming this invention applied thereto.

Figure 2 is a fragmentary longitudinal section through the cottonstripper as applied to the stem of the needle.

5 Figure 3 is a vertical section taken on the line 3-3 of Figure 2; and

Figure 4 is a perspective of the, stripper detached from the needle.

In the drawings, the stripper is shown as applied to a cotton needle orspindle 1 or Well known construction. As shown particularly in Figure 3,this needle is substantially square in cross section; and the facesthereof are provided with flutings 2,

1 0 3, 4 and 5, extending throughout the length of the needle andterminating at a joint 6 from which projects a shank 7 adapted to bereceived in a chuck or other holding device I forming part of the cottonpicking machine. '45 The shank 7 is circular in cross section for thegreater part of that section; and is provided with a flat face 8 adaptedto be received in a correspondingly shaped part of the said chuck toprevent rotation of the needle 1 in said chuck, which is usually rothestripper moves said needle.

'tated in the ordinary cotton picking machine to cause rotation of theneedle 1 They stripper forming the most important part of the presentinvention comprises a cylinder 9 having its outer face 'turneddowntoprovi de an annular flange 10, the shoulders of which form seats andstops for the reception of a pair of washers 11 and 12, which may beshrunk on to the cylinder 9 or otherwise suitably secured thereto as bywelding, soldering or brazing. It is to be particularly noticed that thecylinder 9 is a great deal larger, comparatively, in diameter than thediameter of the spindle 1.

This is purposely made" so in order to prevent jammingof the cylinderson the needle 1 andto facilitate cleaning ofcotton therefromin case thespace between the cylinder and needle should become choked.

. .For the purpose of 'slidably mounting the I cylinder 9 on the needle1, the cylinder is provided with longitudinal slots 13, 14, 15 and 16 toform the projecting arms 17, 18,

19 and 20. These arms are tapered from the inner edge of the slotsadjacent the washer 12, and have their tapered ends rounded ofi to fit 1the'flutings 2, 3., land 5. These arms 17, 18,19 and 20 form thestripper arms;

and'as will be seen from the drawings, slide in the fiutings under thecotton and effective- 1y strip the cotton from the needle whenlengthwise along the The oppositeend of the cylinder 9 is provided withslots 21, 22, 23 and24to form arms 25, 26, 27' and 28 having their outer'ends tapered also to fit in the fiutings of the needle 1. The arms25,26,27 and 28 are shorter than the arms on the other side of thecylinder 9, and they cooperate with such arms to position the washers orflanges 11 and 12 substantially perpendicular to the axis of the spindle1 in order that they may be properly engaged by the elements of a cottonpicking machine (not shown) for --movingthe stripper relatively to theneedle 1. for stripping the cotton therefrom at the proper cycle ofoperation of the said machine. 4 r

The teeth 29qmaybe formed on the corners of the needle by nicking thosecorners or in any other suitable manner. It is immaterial how theseteeth are made, and the size of them is relatively unimportant becausethe comparatively large diameter of the stripper cylinder 9 avoids thenecessity of slotting a stripper in order to accommodate these teeth asthe stripper moves over them.

It will be apparent from inspection of the drawings that I have provideda stripper for a cotton needle which can be very cheaply manufacturedand which cooperates with needles of the fluted type for very efiicientstripping of the cotton therefrom. It will also be apparent that becauseof the comparatively large diameter of the cylinder 9 with respect tothat of the needles, and be cause of the large slots between thestripper arms, there is very little chance for choking or jamming of thestripper on the needle.

It is ObVlOIlS from the foregoing description and drawings that thedetailed arran ement and construction of the various e ements may bemodified considerably without departing from the spirit of the inventionwhich must not be considered as limited strictly to the constructionshown and described.

What I claim is: c

1. A cotton picker needle substantially polygonal in cross section andhaving the faces thereof fluted, and a stripper having a cylindricalbody provided with means projecting longitudinally therefrom in oppositedirections to engage said flutingsfor slidably supporting the saidstripper on said needle.

'2. A cotton picker needle polygonal in cross section and having groovesformed in each face thereof, and a stripper compris ing a body havingspaced apart arms projecting therefrom with the ends thereof seated insaid grooves for slidablymounting the stripperon the needle.

3. A cotton picker needle substantially polygonal in cross section, astripper comprising a cylindrical body of larger diameter thanthediameter of said needle, said body having annular flanges extendingperpendicularly therefrom and spaced apart and having arms extending inopposite direction for slidably engaging the faces of said needles tosupport the stripper on the needle;

4. A stripper for a cotton needle comprising a cylinder having anannular flange formed thereon, a pair of annular discs seated on saidcylinder and against the opposite edges of said flange, and armsseparated from each other and extending lengthwise of said cylinder forslidably mounting the stripper on a cotton picking needle. 1

5. A stripper for a cotton picker needle comprising a cylinder havingits opposite ends slotted to provide arms for engaging and slidablymounting a picker needle in said cylinder and a pair of parallel annularflanges projecting normally from said cylinder between said ends.

6. A stripper for a cotton pickerneedle comprising a cylinder having anannular flange formed on the outer periphery thereof, a pair of annulardiscs secured to said cylinder against opposite edges of said flange,
